One of the first sensor 5 and the second sensor is a transmitter, and the other is a receiver. The fixing component 7 includes a fixing member 71 and an elastic member 72. The electronic component 6 is provided with a first fixing hole 61, and the fixing member 71 and the elastic member 72 are both placed in the first fixing hole 61. One end of the elastic member 72 abuts against the bottom of the first fixing hole 61, and the other end of the elastic member 72 abuts against one end of the fixing member 71. The lock housing 1 is provided with a second fixing hole 12, and the other end of the fixing member 71 protrudes from the electronic component 6 and is placed in the second fixing hole 12. The alarm component 8 is mounted on the electronic component 6, and the alarm component 8 is electrically connected to the first sensor 5 or the second sensor.

[0042] The padlock of the embodiment of the present application includes a lock shell 1, a lock body 21, a lock rod assembly 3, a lock core 4, a first sensor 5, an electronic assembly 6, a fixing assembly 7 and an alarm assembly 8. The first sensor 5 is arranged on the lock core 4, and the electronic assembly 6 is provided with a second sensor. Since one of the first sensor 5 and the second sensor is a transmitter and the other is a receiver, and the alarm assembly 8 is electrically connected to the first sensor 5 or the second sensor, the distance between the first sensor 5 and the second sensor is changed during the rotation of the lock core 4 driven by the key, and the alarm condition is set according to the change in the distance between the first sensor 5 and the second sensor. Through the arrangement of the first sensor 5, the second sensor and the alarm assembly 8, the user can be reminded in time when the padlock is damaged, and the lawbreakers can be deterred, thereby improving the anti-theft performance.

[0043] In one embodiment, the first sensor 5 may be a receiver, and the second sensor may be a transmitter; or the first sensor 5 may be a transmitter, and the second sensor may be a receiver.

[0044] Preferably, in this embodiment, the first sensor 5 is a receiver and the second sensor is a transmitter. When the first sensor 5 is a transmitter, it can be a magnetic field transmitting device, specifically, the magnetic field transmitting device can be a magnet, which is used to generate a magnetic field. The second sensor is a magnetic field receiving device, which is used to sense the magnetic field generated by the magnet and generate a corresponding electromagnetic signal.

[0045] Since the magnet is arranged on the lock core 4, as the lock core 4 rotates, the magnet will also rotate with the lock core 4, changing the position of the magnet, resulting in a change in the position between the magnet and the magnetic field receiving device. When the padlock is in an unlocked state, the distance between the magnet and the magnetic field receiving device is the farthest, resulting in the weakest signal received by the magnetic field receiving device. When in a locked state, the distance between the magnet and the magnetic field receiving device is the shortest, and the signal received by the magnetic field receiving device is the strongest. In this embodiment, an alarm can be set according to the change in the strength of the signal received by the magnetic field receiving device, and the alarm component 8 determines whether to alarm according to the change in the electromagnetic signal. The alarm component 8 includes a speaker 81 and a vibration sensor. The speaker 81 is located at one end of the lock shell 1, and the alarm message is broadcast through the speaker 81.

[0052] When installing the electronic component 6, first press the fixing member 71 to move the fixing member 71 into the first fixing hole 61, and then push the electronic component 6 from one end of the lock housing 1 into the lock housing 1. When the electronic component 6 is installed in place, the other end of the fixing member 71 moves into the second fixing hole 12 under the elastic force of the elastic member 72, thereby locking the electronic component 6. When the electronic component 6 is locked, the two springs 218 are in a compressed state. The installation of the electronic component 6 can be achieved without the aid of tools, and the installation method is convenient and quick.

[0053] When it is necessary to remove the electronic component 6, a steel needle or other tool is used to press the other end of the fixing member 71 to disengage the other end of the fixing member 71 from the second fixing hole 12. At this time, under the elastic force of the two springs 218, the two springs 218 push the electronic component 6 from the lock case 1 to one end of the lock case 1, so that the electronic component 6 automatically pops out of the lock case 1, thereby facilitating the removal of the electronic component 6. A battery is provided on the electronic component 6, and the battery is used to power the second sensor and the alarm component 8. After the electronic component 6 is removed, it is convenient to replace the battery or charge the battery.
